In a typical underground face-drilling scenario, hoses are easily damaged by falling debris and rocks, constituting one of the main causes for drilling stoppages. Crucially, internalising hoses provides protection and can minimise the potential for damage. The internal hydraulics of the two-boom M20 result in a hose-less arrangement aimed at reducing unplanned down time for hose repairs. The absence of hoses can give operators improved visibility from the cabin, thereby enhancing safety.
In addition to drilling, the machine can be turned to rock bolting, during which on-board software logs the position, angle and depth of each bolt installed, thereby improving quality control.
Epiroc has incorporated a suite of smart automation options – such as enabling automated drilling according to digital drill plans which can be conveyed to the rig via USB or Rig Remote Access (RRA). These can result in better precision and productivity for lower cost-per-metre, but also less overbreak and underbreak.
According to Epiroc, the optional zero-emission battery driveline makes the rig the first of its kind to be able to drill partly on battery power.
Following trials at customer sites in Australia, Sweden and Spain, the machine is expected to be commercially available later this year.
